Abstract

The aimed of this study to isolate, select and characterize physically phytase-producing bacteriafrom hot springs in the Guci, Tegal. Isolation and enrichment of bacteria using Lurya Betani mediawith 2% of phytic acid substrate. Extraction of extracellular phytase thus obtained extract coarse andoptimization by loking at the relative activity at the difference in the resulting product. Phytaseproducingbacteria can be isolated from the hot springs of the Guci, Tegal with the highest relativeactivity in AG2 and AG2-1 colonies. The highest relative activity at a temperature of 55°C, pH 6, theincubation time of 90 minutes, the substrate concentration of 3% and a metal cofactor Ca2+ at aconcentration of 10-4M. Phytase-producing bacteria can be isolated from a hot spring in Guci, Tegaland have certain physical characteristics.

Abstract

The scientific work independence is the core competency of student teacher of science. In this research, the effectiveness of the Science Integrated Learning Model (SIL) was measured in term of the scientific work independence of student teacher of science in changing the society’s original knowledge into scientific knowledge. The changing was measured through Ethnoscience learning. The experimental method was used with the control group and experimental group in three different universities. The result of the t-test shows a correlation coefficient significance value at 0.000 < 0.05. Therefore, it concludes that there is not any difference between the experimental and control group. However, there is an effect of model application on the independence of the scientific work of student teacher of science.

Abstract

Learning science is not limited to reviewing the concepts, but strengthens the identity of a nation that has a diversity of cultures. Science learning objectives that have been set in Indonesia, including the student is able to apply the science wisely, to maintain and preserve the cultural survival. The study aims to measure students' ability to relate concepts of science with local knowledge to use mind maps compiled individually. The results showed that 85% of teacher candidates are able to determine the relationship of science and local knowledge correctly. The ability to link the two domains, through the literature review, observation and interviews.

Abstract

The reseach purpose is to compare learning proportion of the students based on arguments to learners Claim which is supported by facts, data and theories between conventional learning and PBL as the answers for teacher questions. Research Procedure began with 4 times biology teachers discussion workshops to compile PBL learning plan to be used on treatment class. 61 participants with 30 in control class and 31 in treatment class. Reasoning calculation based on arguments during communication in form of the answers to teacher questions. Basic Grouping of Learning is : Claim Rebuttal (CR), Claim Data (CD), Claim Backing (CB) and Claim (C). Results indicates that: C decreases during PBL learning; CB increases during PBL; CD  doesn’t exhibit real change during PBL. PBL utilization needs the readiness and competence of the teachers which influences the reasoning quality of the learners.

Abstract

Scientific argumentation skill required to be mastered in this era. Unfortunately many students still have strunggle improving their scientific argumentation skills. This study was aimed at describing the effectiveness of ecosystem module grounded in Problem-Based Learning in improving scientific argumentation skills. This research was part of the field testing of R&D, a research and development previously conducted. Research participants included tenth grade senior high school students. Two classes were selected as a control and experiment class. The control class (existing) did not use the module but the experiment class use the module (module class) grounded in Problem Based Learning implemented. Data were collected from written tests and observations. Data analysis used the scoring rubric of scientific argumentation skill aspect which their results were tested with Gain test and independent T-test. The findings showed an increase in scores of the four aspects of scientific argumentation skills from the module class. The highest percentage of aspect was rebuttal aspect (27.27%) followed by evidence 26,06% and reasoning 23.94%, while the aspect of claim increased by 20.61%. The independent t-test results showed that there was a significant difference between pre-test and post-test results of the module class. It can be concluded that the ecosystem module with problem-based learning material was effective to improve students’ scientific argumentation skills. The product of this reasearch can be use as a tools to improve students’ scientific argumentation skills.
